在 VS Code 中调试
本指南将引导您完成设置 VS Code 以调试 Tauri 应用的核心进程。
所有带有 vscode-lldb 扩展的平台
先决条件
安装 vscode-lldb
扩展。
配置 launch.json
创建一个 .vscode/launch.json
文件并将以下 JSON 内容粘贴到其中
{ // Use IntelliSense to learn about possible attributes. // Hover to view descriptions of existing attributes. // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387 "version": "0.2.0", "configurations": [ { "type": "lldb", "request": "launch", "name": "Tauri Development Debug", "cargo": { "args": [ "build", "--manifest-path=./src-tauri/Cargo.toml", "--no-default-features" ] }, // task for the `beforeDevCommand` if used, must be configured in `.vscode/tasks.json` "preLaunchTask": "ui:dev" }, { "type": "lldb", "request": "launch", "name": "Tauri Production Debug", "cargo": { "args": ["build", "--release", "--manifest-path=./src-tauri/Cargo.toml"] }, // task for the `beforeBuildCommand` if used, must be configured in `.vscode/tasks.json` "preLaunchTask": "ui:build" } ]}
这直接使用 cargo
来构建 Rust 应用程序并在开发和生产模式下加载它。
请注意,它不使用 Tauri CLI,因此不执行独占 CLI 功能。beforeDevCommand
和 beforeBuildCommand
脚本必须事先执行,或在 preLaunchTask
字段中配置为任务。以下是一个 .vscode/tasks.json
文件的示例,该文件有两个任务,一个用于生成开发服务器的 beforeDevCommand
,另一个用于 beforeBuildCommand
{ // See https://go.microsoft.com/fwlink/?LinkId=733558 // for the documentation about the tasks.json format "version": "2.0.0", "tasks": [ { "label": "ui:dev", "type": "shell", // `dev` keeps running in the background // ideally you should also configure a `problemMatcher` // see https://vscode.js.cn/docs/editor/tasks#_can-a-background-task-be-used-as-a-prelaunchtask-in-launchjson "isBackground": true, // change this to your `beforeDevCommand`: "command": "yarn", "args": ["dev"] }, { "label": "ui:build", "type": "shell", // change this to your `beforeBuildCommand`: "command": "yarn", "args": ["build"] } ]}
现在您可以在 src-tauri/src/main.rs
或任何其他 Rust 文件中设置断点,然后按 F5
开始调试。
在 Windows 上使用 Visual Studio Windows 调试器
Visual Studio Windows 调试器是一个仅 Windows 的调试器,通常比 vscode-lldb
更快,并且对某些 Rust 功能(如枚举)具有更好的支持。
先决条件
安装 C/C++ 扩展,并按照 https://vscode.js.cn/docs/cpp/config-msvc#_prerequisites 安装 Visual Studio Windows 调试器。
配置 launch.json 和 tasks.json
{ // Use IntelliSense to learn about possible attributes. // Hover to view descriptions of existing attributes. // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387 "version": "0.2.0", "configurations": [ { "name": "Launch App Debug", "type": "cppvsdbg", "request": "launch", // change the exe name to your actual exe name // (to debug release builds, change `target/debug` to `release/debug`) "program": "${workspaceRoot}/src-tauri/target/debug/your-app-name-here.exe", "cwd": "${workspaceRoot}", "preLaunchTask": "ui:dev" } ]}
请注意,它不使用 Tauri CLI,因此不执行独占 CLI 功能。tasks.json
与 lldb
相同,只是您需要添加一个配置组,并将 launch.json
中的 preLaunchTask
定位到该组,如果您希望它始终在启动前编译。
这是一个运行开发服务器(相当于 beforeDevCommand
)和编译 (cargo build
) 作为组的示例,要使用它,请将 launch.json
中的 preLaunchTask
配置更改为 dev
(或您命名的任何组)。
{ // See https://go.microsoft.com/fwlink/?LinkId=733558 // for the documentation about the tasks.json format "version": "2.0.0", "tasks": [ { "label": "build:debug", "type": "cargo", "command": "build" }, { "label": "ui:dev", "type": "shell", // `dev` keeps running in the background // ideally you should also configure a `problemMatcher` // see https://vscode.js.cn/docs/editor/tasks#_can-a-background-task-be-used-as-a-prelaunchtask-in-launchjson "isBackground": true, // change this to your `beforeDevCommand`: "command": "yarn", "args": ["dev"] }, { "label": "dev", "dependsOn": ["build:debug", "ui:dev"], "group": { "kind": "build" } } ]}
